Abstract

Abstract: This paper first analyzes the main forms of vacuum precision casting furnace both at home and abroad,and discusses the shortcomings of these forms in the face of large precision casting. Then,in view of these shortcomings,a new structure layout for large vacuum precision casting furnace and its derivative furnace are proposed.Finally,the development opportunity and prospect of this new structure layout are discussed.

Key words: large size precision casting, superalloy, equiaxed crystal casting, vacuum presicion casting furnace

CLC Number:

TF341.7
